INSULATOR PIN AND BRACKET.

SPECIFICATION forming part of Letters Patent No. 701,246, dated May 27,1902.

Application filed March 25, 1902. Serial No. 99,938. (No model.)

To ctZl whont it may concern:

Beit known that I, ELBERT T. BAILY, a citizen of the United States,residing at Mount Kisco, in the county of 'Westchester and State of NewYork, have invented certain new and useful Improvements in InsulatorPins and Brackets; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame. 5

My invention relates to an improvement in insulator-pins and is embodiedin the construction and arrangement of parts presently to be described,and defined in the claims.

The invention relates more particularly to that class of devices-such aspins, brackets, or pegs-for supporting and carrying conductors, such asoverhead conductors, and it is designed more particularly for use inconnection with cross arms or poles or other supports; and the object ofthe invention is to provide a pin which can be quickly adjusted andapplied, one wherein metal can ,be employed in its construction, a pinor carrier which will securely hold the insulator against accidentalmovement or escape, which can be cheaply manufactured, and'which in itsapplication will avoid the necessity of boring or drilling thesupporting member to which the same is attached.

Other objects and features of the invention will presently be stated.

In the accompanying drawings I have shown a preferred form andmodification of the invention; but it is to be understood that thegeneralprinciple and nature of the invention can be applied in variousways and With various forms of construction other than those shown.

Figure 1 is an elevation of the cross-arm of a supporting-pole, showingthe improved pin thereon. Fig. 2 is a side elevation of the same. Fig. 3is a detailed section through the yielding supporting-arms of the pin.Figs. 4, 5, and (3 are modified forms of the construction shown inFig. 1. Fig. 7 illustrates a modified form of the invention, the samebeing in the form of a bracket or attachment to the side of the support.

A designates a cross-arm of a supportingpost, which is constructedconveniently with a longitudinal channel B therein.

0 O designate two independent pin-sections arranged and fashioned sothat when in proper relation they constitute the pin. These members 0and O are conveniently constructed ofmetal, having the lowerangularportions 0 with upturned ends fitted in the groove B. The port-ions care connected to the vertical portions 0, which are extended upward andbent inward obliquely and thence upward at an oblique angle, formingthereby spring or yielding extensions 0 The extensions c carry on theirupper ends semicylindrical threaded insulating-blocks 0 the threadsbeing on the outer face only, while the inner faces iit the sides of theextensions. To secure the blocks in place, recesses e are formed neartheir upper ends, into which the turned over ends e of the extensionsfit. Other means may, however, be employed for that purpose. Between theextensions may be placed a wood or insulated filler-strip 0 (see Fig.6,) which has a threaded edge corresponding with the threads of theblocks 0. D designates the insulator, of a well-known form andconstruction,screw-threaded on the threaded portions of the pin.

The construction above described is such that by embracing the sides ofthe arm A closely the upper ends of the pin will be separated andbysecuring the insulator thereonto the parts will be drawn close together,and owing to the yielding spring nature of the material of which the pinmembers or sec tions are constructed there will be a constant bindingtendency between the insulator and the pin, thus serving to firmly holdthe insu-.

lator in place. To add to the rigidity or strength of the upper portionsof the pin,suitable braces o are formed along the outer faces of theoblique portions. These braces may be secured to the metal of the pins,but preferably are formed by rolling or striking up the metal of thepins between the edges, forming thereby crimps or strengthening bends.To adjust the pin on the arm A, it is only necessary to place thedifferent members thereof in position and then clamp them in position byscrewing on the insulator. It may, however, be found convenient in somecases to pass screws or nails, such as E, through the upright portionsof the pin members into the arm A.

A modification of the construction above described is illustrated inFigs. 1-, 5, and (5. In the former the pin is constructed of a singleband 0 spanning the bottom of the arm, as shown at E. In Fig. 5 the pinmembers are similar to those shown in Fig. 1, except the channel in thearm A is omitted and the struck up ends of the lower portions care inthe form of brads or teeth, which penetrate the material of the arm. InFig. (i I have shown a construction whereby the members of the pin areconstructed without the lower angular portions, the bent-in ends takinginto the longitudinal grooves h in the sides of the arm A. In thisconnection Ihave found itconvenient in some cases to substitute for thethreaded wooden blocks of the pin metallic structures, as G, the samebeing formed of concavo-convexed extensions of the upper portions of thepin, their outer faces being threaded. An interposed wood filler C maybe used. In Fig. 7 the invention is shown in the form of abracket,wherein the two pin members II II are connected at their outerends, as at It, from which point they diverge outwardly and terminatingin securing portions 7L. On the sides of the pin are theinsulating-blocks II 11*, conveniently of wood, the same being securedin position by having struck-up or otherwiseformed ledges 7L2 7L3projecting from the sides of the different branches of the pin. Byforcing the insulator onto the pin the diverging arms thereof are forcedtogether and the spring effect of the construction shown in Fig. 1 isattained.

By the construction above described I am enabled to secure aninsulator-pin to the support without puncturing or boring out thesupport, as is the case when a wooden pin is used. I also largelyprevent the pin from becoming loose on the cross-arm.

The invention is also designed for application to various forms of armsor supports and can be of a shape to fit various angles. It is alsoapparent that in the art of manufacturing the pins can be made at arelatively small expense.

I desire to call particular attention to the arm having a channel in itsunder face, as I have found that such a construction enables theapplication of the pin, as above described, at any point on the arm andpermits the application of the pin between two wires, itsadjustmenttoward and from adjacent wires, and its removal withoutinterfering with the adjacent wires. It is also apparent that an arm ofless diameter than those now in use can be employed, thus doing awaywith a large amount of weight and superfluous timber.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is-
